Revision as of 14:08, 21 October 2010

Elections to the United States Senate are scheduled to be held on November 2, 2010, for 37 of the 100 seats in the United States Senate. A special election for a 38th seat was held in Massachusetts on January 19, 2010, for a term that ends in January 2013.

Thirty-four of the seats are for six-year terms, beginning January 3, 2011, and ending January 2017. They will join Senate Class III, which traces its roots back to the senators who served full six-year terms from March 4, 1789 to March 3, 1795. The other three races are for shorter terms: Delaware ending January 2015, New York ending January 2013 and West Virginia ending January 2013.

After the 2008 elections and their subsequent events, the Senate is composed of 57 Democrats, 41 Republicans, and two independents who caucus with the Democrats. Of the remaining seats up for election in 2010, 19 are held by Democrats (seven of whom are retiring or were defeated in the primary) and 18 are held by Republicans (eight of whom are retiring or were defeated in the primary).

Democratic incumbents defeated in primary election (1 seat)

Arlen Specter of Pennsylvania

Five-term incumbent Democrat Arlen Specter had been reelected as a Republican by a 53% to 42% margin in 2004.^[87] On April 28, 2009, Specter announced that he would leave the Republican Party and seek a sixth term in 2010 as a Democrat.^[88]

Based on polling, the 2004 primary results and a smaller, more conservative Pennsylvania Republican primary electorate, Specter judged that he would lose the Republican primary, and since Pennsylvania law would bar him from running as an independent under such circumstances, he decided to switch parties. As a long-standing moderate, Specter had had tensions with the conservative base of the GOP dating back to 1987 when he played a key role in derailing President Ronald Reagan's nomination of Robert Bork to the U.S. Supreme Court. Recently, Specter had further antagonized the GOP base in Pennsylvania by voting in favor of the American Recovery and Reinvestment Act of 2009 otherwise known as the Economic Stimulus Bill. In return for joining the Democratic Party, President Barack Obama, Vice President Joe Biden, Governor Ed Rendell and Senate Majority Leader Harry Reid all discouraged candidates from challenging Specter in the Democratic primary.

Retired U.S. Navy Rear Admiral and current U.S. Representative Joe Sestak of Pennsylvania's 7th congressional district announced on August 4, 2009, that he would challenge Specter for the Democratic nomination despite the support for Specter amongst the Democratic establishment.^[89] Specter was thought to be favored until polls two weeks before the Democratic primary began showing a dead heat between him and Sestak.^[90] On May 18, 2010, Sestak defeated Specter in the Democratic primary by a 54% to 46% margin.^[91]

On the Republican side, former U.S. Representative and former President of the Club for Growth Pat Toomey, who came within 1.7 percent of defeating Specter in the 2004 GOP primary, announced that he would run for the Republican nomination. Former Governor and 2008 Republican presidential candidate Mitt Romney has endorsed Toomey.^[92] Other Republican candidates include businessman Larry Murphy,^[93] who challenged Specter in the 1998 GOP Senate primary, 1994 and 1998 Constitution Party gubernatorial candidate Peg Luksik,^[94] and retired Federal Air Marshal Robert Townsend.^[95]

In 2008, Barack Obama received 54.47 percent of the vote in Pennsylvania while John McCain received 44.15 percent, a 10.32-percent margin of victory for the Democrat.^[96]

Republican incumbents defeated in primary election (2 seats)

Lisa Murkowski of Alaska

Incumbent Republican Lisa Murkowski, who was appointed in 2002 by Governor Frank Murkowski (her father), was reelected to a full term in 2004 with 48.6% of the vote.^[97]

Murkowski announced that she would seek reelection with fundraising aid from former Governor Sarah Palin.^[98] However, Palin endorsed and supported Joe Miller in the Republican primary election campaign. After the primary votes were counted on election day, August 24, Joe Miller was barely ahead. However, the absentee ballots were not counted until a week later, on August 31. With the absentee votes counted, Miller defeated Murkowski in the primary. Murkowski conceded the election to Miller following the counting of the absentee ballots.^[99]

On the Democratic side, Mayor Scott McAdams (Sitka) was nominated in the primary.

On September 17, 2010, Murkowski announced that she would run a write-in campaign against Miller and McAdams.^[100]

In 2008, John McCain received 59.42% of the vote in Alaska while Barack Obama received 37.89%, a 21.53-percent margin for the Republican.^[101] In the 2008 senate election, Democrat Mark Begich with 47.77% of the vote beat incumbent Republican Ted Stevens with 46.52% of the vote due to an ethics scandal.

Bob Bennett of Utah

Three-term incumbent Republican Bob Bennett was reelected with 69 percent of the vote in 2004.^[102] Bennett intended to run for reelection.^[103] In May 2009, Bennett released an early advertisement, in which Mitt Romney expressed his support for Bennett, to discourage a primary challenge.^[104]

At the May 8 Republican nominating convention, Bennett was defeated, finishing third in the balloting and resulting in him not being eligible to run in the Republican primary that was held June 22, 2010 and featured the top two finshers, Tim Bridgewater and Mike Lee. Bennett's defeat in the convention somewhat raised Democrats' hopes of winning the seat in this heavily Republican state.^[105] In a mild surprise, Lee narrowly won the Republican primary and will face Utah Alcoholic Beverage Control Commission Chairman Sam Granato in the general election.^[106]^[107]

In 2008, John McCain received 62.24 percent of the vote in Utah while Barack Obama received 34.22 percent, a 28.02-percent margin of victory for the Republican.^[108]

Democratic incumbents (12 seats)

Lincoln received a tough primary challenge from Lieutenant Governor Bill Halter who entered the race on March 1, 2010^[111] and raised more than $1 million in his first 48 hours.^[112] In the primary, Lincoln finished with less than a majority and faced a runoff with Halter. On June 8, Lincoln won the runoff by a 52% to 48% margin.^[113]

In the Republican primary, U.S. Representative John Boozman of Arkansas's 3rd congressional district based in Northwest Arkansas finished with an absolute majority to become the Republican Senate nominee.^[114]

In 2008, John McCain received 58.72 percent of the vote in Arkansas while Barack Obama received 38.86 percent, a 19.86-percent margin of victory for the Republican.

Barbara Boxer of California

Three-term incumbent Democrat Barbara Boxer (D) was reelected with 58 percent of the vote in 2004,^[119] but had difficult races in 1992 and 1998. In February 2007, she announced that she would seek a fourth term in 2010.^[120] Boxer won the Democratic Senate primary on June 8 with 80 percent of the vote. "The surprise runner-up: Hollywood producer Brian Quintana, who snatched almost 15% of the vote."^[121] Blogger Mickey Kaus received the remaining 5%.

Boxer is facing a very tough challenge from her major opponent, Republican businesswoman Carly Fiorina, according to several recent polls.^[122] Fiorina, former Hewlett-Packard CEO, defeated State Assemblyman Chuck DeVore, as well as former Representative Tom Campbell, for the Republican Party nomination.

Donald J. "Don" Grundmann has filed paperwork for the American Independent Party nomination.^[47]

Jerry L. Carroll has filed as an independent.^[47]

In 2008, Barack Obama received 60.94 percent of the vote in California while John McCain received 36.91 percent.^[119]

The last time California elected a Republican to the U.S. Senate was in 1988, when Pete Wilson won a second term. He resigned in 1992 upon being elected governor, and the state has since had both its Senate seats occupied by Democrats.

Michael Bennet of Colorado

Following the resignation of one-term U.S. Senator Ken Salazar (D) to become President Barack Obama's Secretary of the Interior,^[123] Governor Bill Ritter selected Michael Bennet, the former Superintendent of Denver Public Schools, to fill Salazar's seat for the remainder of his term.^[124] Bennet won his party's nomination in the August 10, 2010 primary election, fighting off a stiff challenge by former Speaker of the Colorado House of Representatives Andrew Romanoff.^[125] Romanoff received the endorsement of former President Bill Clinton while Bennet has been endorsed by President Obama.
